IMPROVEMENT IN VEHICLE-SEAT FASTENERS.

Specification forming part of Letters Patent No. 194,513, dated August 28, 1877 application filed July 12, 1877.

To all whom it may concern:

Be it known that I, WILLIAM J. ELSOM, of Cortland, county of Cortland, and State of New York, have invented certain new and useful Improvements in Vehicle-Seat Fasteners, of which the following is a clear, full, and exact description, reference being had to the accompanying drawings, making a part hereof, in which- I Figure 1 is a plan of my device, and Fig. 2 is an edge view.

Like letters refer to like parts in both figures.

D represents the seat riser or support, and E the rail or frame-work, of a carriage.

My device consists, essentially, of three principal parts: a supporting-plate, A, a tierod, B, and a cam-lever, (l. r

The supporting-plate Aconsists of the baseflange a which is extended in such a manner as to form a slot or way for the reception and operation of the tie-rod B, and farther extended to form a bracket, a and hub 0;, Fig.2, for the support and bearing of the cam-lever O, and is constructed of one piece of metal.

The'base-flange a is provided with apertures for the reception of screws or bolts, for the purpose of attaching the supportingplate to the seat-riser. A screw, 0, is also passed through the hub 01; as a further means a of attachment, though I may dispense with it without departing from the spirit of my invention.

The tie-rod B consists of a double hook, the body of which is round, and fits more or less loosely the sockets a, formed in the supporting-plateA. Its lower extremity is formed into a serrated straight branchor hook, B and its upper extremity into a hook, B, of circular contour and smooth bearing-surface,

adapted to receive and be operated upon by the cam-lever G. This hook B extends in a direction at right angles to that of the hook B The cam-lever O is provided with a flange, 11, upon its outer face, and a depression, 0,

on its cam-face, as shown in dotted lines in Fig. 1, and apart from those indicating the cam-lever in an upright position.

The operation of my device is as follows: The lever G is raised to the position indicated by the dotted lines in Fig. 1, and the tie-rod turned in its socket until the hook B extends at a right angle from the seat-riser. The seat is then placed upon the body of the carriage or other vehicle, and the tie-rod turned until the hook B lies against the riser and over the cam. This position of the hook B determines the position of the hook B to be beneath the rail E of the carriagebody. The lever O is now depressed, the hook B being retained in its position on the cam by the flange d, the hook B clamping the rail E, and retained in position by the serrations upon the binding-face of the hook B The depression of the cam-lever G binds the riser to the rail, and at or near the end of its throw a further depression causes the extreme end of the hook B to drop into the depression 0 for the purpose of locking the lever G in such position against all liability of its becoming loosened accidentally. A reversal of these directions serves to release and detach the seat from the carriagebody. W

It is evident that all of the three parts of my construction are not absolutely essential to an operative device, because I may dispense with the supporting-plate, and by means of the double hook and cam-lever, provided with the flange d, to hold the lever in position, I may firmly secure the seat to the rail. In like manner 1 may or may not dispense with the depression 0 upon the face of the cam.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The hook B B and B in combination with the cam-lever 0, provided with the flange d, substantially as shown and described.

2. The hook B B 13, in combination with the cam-lever 0, provided with the flange d- A', book B B B cam-lever 0, provided with and depression 0, substantially as shown the flange d, and depression 0, as shown and and described.

3. Dhe combination of the supporting-plate A, having the hub an integral therewith, the hook B B B and the cam-lever 0, provided with the depression 0', as shown and described.

4. The combination of the supporting-plate described.

In witness whereof I have hereunto set my hand this 6th day of July, 1877.
